Topsøe: Two SNOX plants for Petrobras  

By Gerald Ondrey |

Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) has signed an agreement with the Brazilian oil company Petrobras for the supply of critical equipment and materials for two SNOX plants. The plants will be installed at the new RNEST grass root petroleum refinery in Pernambuco, Brazil. The supply covers internals for 80 WSA condensers for condensation of sulphuric acid, eight units for acid mist control and a complete acid system. The SNOX plants will clean the off gases from three boilers in the refinery that supplies electricity and steam for internal use. The boilers are fired with heavy fuel oil and petcoke. Based on catalytic processes the SNOX technology converts sulphur dioxide to industrial grade sulphuric acid and NOx to harmless nitrogen. In addition to treating the boiler fluegases, the Claus plant tail gases, the amine gases containing hydrogen sulphide and the SWS gases containing ammonia will also be treated in the SNOX plants. The SNOX plants are designed for possible elimination of the Claus plants, which then means that all sulfur compounds in the refinery are converted into sulphuric acid. The two SNOX plants will be installed in parallel and will each treat up to 650,000 Nm3/h of fluegas while producing up…
